What would have been so useful is expanding mapfile to associative arrays:

    key${IFS}value

    declare -A assoc
    IFS='= ' mapfile -t assoc <<INFILE
    key1 = value1
    key2=value2 with spaces
    INFILE

And some dream of mapping JSON object members to associative arrays:
    mapfile -j assoc <<JSON
    {
      "key1": "value1",
      "key2": 42,
      "key3": {
                "otherkey": "othervalue"
      }
    }
    JSON

translated to:

    declare -A assoc(["key1"]="value1" ["key2"]="value2" ["key3"]=$'{\n 
 "otherkey": "othervalue"\n}'
